To assess whether ankle tape applied by a Sport and Exercise Physiotherapist (SEP) or self-applied by the athlete results in a change in proprioception and whether it is maintained during a netball session.
Randomised controlled trial.
Australian Institute of Sport.
53 pre-elite netball athletes.
Athlete proprioception was assessed using the Active Movement Extent Discrimination Apparatus (AMEDA) on four occasions for each taping condition 1) pre-tape, 2) post-tape, 3) post-netball &amp; 4) post-netball no-tape.
Mixed effect linear models were used for analysis. A significant increase in proprioception was observed when self-tape 0.022 (95% CI [-0.000 - 0.044], p=0.05), and SEP tape 0.034 (95% CI [0.012-0.055], p&lt;0.01), were initially applied. https://www.selleckchem.com/products/Estrone.html These improvements were maintained during a netball session for both, self-taping 0.01 (95% CI [-0.01 - 0.02], p=0.45) and SEP-taping &lt;0.01 (95% CI [-0.02 - 0.01], p=0.56). Results also indicate there was no significant difference between taping conditions (β=-0.001, 95% CI [-0.02 - 0.02], p=0.90).
Proprioception improves and is maintained during a netball session with either SEP or self-applied taping.

Delphi-validated questionnaire.
Online.
Eighteen high-performance managers of the Australian Football League.
Descriptive statistics were collected to establish experience; central themes were established for the analyses of the beliefs and practices.
Nine (50%) physical performance coaches responded to an invitation to complete the questionnaire. Participants held an undergraduate degree and had 9.2±4.3 years of experience. Accelerations (n=9), maximum speed sprints (n=9) and running with hip flexion (n=7) were the most common activities associated with HSI. Coaches believed sprinting, eccentric strength training and proper periodisation were effective strategies to reduce HSI risk. There's a disparity between beliefs and practices when using GPS to monitor sprinting, however, all coaches reported regular exposure to sprint training across both pre and in-season. Overstriding (n=9) and pelvic instability (n=6) were identified as key flaws in running mechanics.
This information can be used to improve training strategies, whilst these findings indicate further investigations into sprint training and running mechanics for HSI risk reduction.

Cross-sectional design. All participants completed a battery of strength (isokinetic, isometric, and repetition to failure) and functional assessments on two occasions. Concurrent validity to isokinetic testing was assessed, and intra-rater, inter-rater, and absolute reliability were established for all assessments.
Controlled clinical environment.
Thirty healthy adults active in recreational sports participated, mean age 24.0±1.6 years; MAIN OUTCOME MEASURES Correlations (Pearson's r), reliability (Intraclass Correlation Coefficient), Standard error of the measurement, Minimal detectable change.
Correlations to isokinetic assessments at 60° &amp; 180°/second were moderate to strong for isometric (r 0.68-0.80) and functional testing (r 0.55-0.83) and weak for repetition to failure testing (r 0.37-0.74). All isokinetic (ICC 0.88-0.94), isometric (ICC 0dity and reliability. Further refinement to the methods used to assess muscular endurance is needed to improve reliability. This study offers clinicians information that can be utilized in clinical decision-making as it relates the testing battery's psychometric properties.Aerosol-cloud interactions and feedbacks play an important role in modulating cloud development, microphysical and optical properties thus enhancing or reducing precipitation over polluted/pristine regions. The lockdown enforced on account of Covid-19 pandemic is a unique opportunity to verify the influence of drastic reduction in aerosols on cloud development and its vertical distribution embedded in identical synoptic conditions. Cloud bases measured by ceilometer in Delhi, the capital of India, are observed to propagate from low level to higher levels as the lockdown progresses. It is explained in terms of trends in temporal variation of cloud condensation nuclei (CCN) and precursor gases to secondary hygroscopic aerosols. The large reduction (47%) in CCN estimated from aerosol extinction coefficient during the lockdown results in upward shift of cloud bases. Low clouds with bases located below 3 km are found to have reduced significantly from 63% (of total clouds distributed in the vertical) during pre-lockdown to 12% in lockdown period (less polluted). Cloud base height is found to have an inverse correlation with CCN (r = -0.64) and NO2/NH3 concentrations (r = -0.7). The role of meteorology and CCN in modulating the cloud vertical profiles is discussed in terms of anomalies of various controlling factors like lifting condensation level (LCL), precipitable water content (PWC) and mixing layer height (MLH).Green innovation (GI) is an important way to realize the sustainable development. This paper contributes to the existing literature by analyzing the effects of different environmental regulations on green innovation from a heterogeneous perspective. We also compare the impacts of indigenous innovation input and foreign technology spillover on green innovation. The dataset of this paper covers a panel of China's 30 provinces from 2003 to 2017. The results of Systematic Generalized Method of Moments (SYS-GMM) show that command-and-control regulation (CER) and informal regulation (IER) have significant "Porter's effect" on green innovation while market-based regulation (MER) negatively affects green innovation in China. Inward foreign direct investment (IFDI) plays a positive role in developing China's green innovation thus, validating the "Pollution Halo hypothesis". Outward direct investment (OFDI) has a reverse green technique effect on China's green innovation. In addition, the positive effect of indigenous innovation input on green innovation is larger than that of foreign technology spillover from IFDI and OFDI.
